Until around 1988-89, Garland Deaderick, the care taker at that time took care of the other gardens on the property. When the gardens weren't getting enough care, Carolyn Nelson started to garden in some of the other areas. Around 2001 the club gradually took on the gardens and some of the yard and the care taker of the museum watered the beds. Among the members who worked throughout the years at the Laramie Plains Museum gardens besides Carolyn were Jan Cartwright, Blanche Sanders, Janet Shively, Ruth McNamee, Erica Gnapt and others, Angela and Andy Faxon, Dona Coffey, Frank Mesa, Rebecca Taylor, Inga Kjartan, Pat Kiovsky, Barb Rouse, Nancy Smueles, Annie Nelson, Doris Eyestone, Dorothy Moore, Sascha Lodge, and Carol and Steve Hoff.
In 2004-2005 the garden which is northeast of the carriage house was established by the club and a grant from the Laramie River Conservation District was obtained. Pat Kiovsky was instrumental in this project. The plaques on the stone are of thanks to the Laramie Garden Club and Carolyn Nelson, head gardener and curator of the museum from 1990-1998; the Laramie River Conservation District; to Greta Neubaur who in the 1960's single-handedly maintained the Ivinson Grounds known as "Greta's Garden"; and to Dorthea Moen who was Ivinson Mansion housekeeper from 1888-1900 and was the great-grandmother of Mark Moen, the donor of the flagstone for the garden path. Mike Snow donated the irrigation system for the garden. The garden became known as the "Garden Path" and contains shade and herb plants.
In 2011 the Laramie Women's Club established a fragrance garden on the southwest corner of the Alice Hardy Stevens center. It surrounds a flagstone area that can be used for seating.
The intent of the museum gardens is to contain heirloom flowers from around the time period when the mansion was built in 1893. Many of the flowers in the gardens were referenced in Restoring American Gardens 1640-1940. Flowers, such as roses, clematis, lilies, foxgloves, Maltese cross, poppies, phlox, hostas, iris, hollyhocks, peonies, and many more are found in the gardens.
